7 f1 ol imfiioi. 139537) I This invention relates to bean threshing ma:chines and the object of the invention is to provide a machinehaving ahopper into which bean plants may be thrown and which will shred thebean pods and will separate the beans from the hay and discharge thebeans to a conveyer from which the beans V w within the hopperl and isprovided with spikes t may be sacked. V v

Another object of the invention is toprovide a bean threshing machine inwhich the beans are separated from the hay. and other foreign matter andare then screened and while being screened, air currents are blowntherethrough to carry off the'finer foreign matter from the beans andthecleaned beans are carried to a 'conveyer which discharges the beansinto a sacking device.-

Another object of the invention is to provide a compact andcomparatively cheap bean threshing machine which has all the advantagesof the larger bean threshing machines.

A further'object of the invention is to pr ovide an arrangement wherebythe hay is discharged at one point from the'machine while the beans aredischarged at anotherpoint'and-the. finer foreign matter and cull beansare discharged atv another point. 1 A further object'of the invention isa bean threshing machine in which all of the parts are driven from asingle pulley to which construction by which these objects are attainedis shown in the accompanying drawings in which- Fig. '1 is anelevationof one side of a bean threshing machine embodying my invention.I

V Fig. 8 is a section taken on line 8--B of Fig. 51. Fig. 9 is a planview of the bean trough shaker also shown in Fig. 2.

As shown in Figs. 2 and 3, a shaft l is provided to provide Fig. 5 is anelevation of the hay discharge end of the machine.

thrown anda drum 5 is attached to the shaft l adapted to pass betweenthe spikes l in the bottom of thehopper'to shred the bean pods and beanplants. Beneath the drum 5, the hopper is provided with openings 8through which the loosened beans m-aydrop onto the belt 9.

shaft'l 8 a shredding .drurn i2 is provided adapted to further. shredtheplants and the beans from this, shredding operation may p-assthrough theapertures. I3 in the bottom of the hopper onto the belt 9. At the end,is provided with a P end portions or teeth extendingbetween the toothedbars of a vibrator rack Hi. The shredded bean plants thrown into thehopper are diischarged from the shredding drum 5 to the shred ding drumI2 and thence' to a feeding drum M3 on the shaft [.1 which is driven byabelt it from the shaft Iii. This feeds the shredded ma: terial onto therack l5 which is slidably supported on the. tudinally by roller 24attached thereto and driven by the belt 9.- This rackyl5 is thus given avibratory longitudinal movement to fluff the shredded material and'atthe .same time the feeder drum to feeds the material longitudinally ofthe toothed frame members of this rack. The rack i5 is 7 provided with awire screen extending from the end thereofover} which the materialpasses during; feedingand the material falls off from v the bottom ofthe hopper sloping partition I l having and 2, a second shaft to extendsthrough the hopper and is driven by a belt H' from a pulley on the shaftI and on this 30'- guide 59 and is vibrated longithe'arin 2B secured tothe shaft 18' which is oscillated by means ofa rod 2! shown I this endof the rack 15 onto the discharge racks.

There are three discharge racks provided 25, 26;

and 21 which are shown in Figs. 3, 4, 5, and 7.

The discharge rack 25 is-sec'ur'ed to -a shaft 28 while the dischargerack 26 is secured to a shaft 29 and the discharge rack 2! is'secured toa shaft 39. These racks swing on their axes from the position shown inFig. 4 to the position shown in Fig. '7 and thence'back to the positionshown in Fig. 4, As will be understood from Fig. 4, the;

material falls onto the rack 25 which is formed from longitudinal slatsand by the turning of this rack to the position shown in Fig. 4, thematerial is thrown onto the rack 26 which turns to the position shown inFig. 7 and. throws the material onto the rack 21 which when turned tothe position shown in Figs 4 discharges the hay from the end of themachine. By thus tossing the hay with these discharge racks, the hay isfiufied to allow the remaining beans' tofall "onto the screen 32, ontowhich beansxare also discharged by the conveyer belt 9 which is providedwith transverse slats 33 which carry the beans to. the screen 32. Thisbelt 9 at the discharge end is provided with a roller 34 securedto theshaft 35 and as shown inFig. 2 apulley. 36" is secured to the shaft 35and is driven by the belt 31. The opposite end of this shaft 35 isprovided with an arm 33 shown inFig. 6 which, during rotation of theshaft, oscillates a rod 39 connected to an arm 40. This arm 48 issecured to the shaft 29 and an arm 4! is secured to this shaft- 29 andis provided witharms 42 and 43 connected to opposite ends thereof whichoscillate the shafts 28 and 30 by means of the arms 44 and 45. By thisarrangement, the movement of the discharge racks from the positionshownin Fig. 4 to that shown inFig. '7 is accomplished and the' movement'ofthe various arms to'move the discharge racks is illustrated in Figs. 1-and 6.

As arm 46 is pivotally connected tofthefree end of the arm 45 and inturnis pivotal ly" connected to an arm 41 which is secured tothe shaft @8.This shaftj48 as shown iii-Fig, 7 extends beneath the screen box 49 andis provided with a short arm 50 which'is pivotally connected to-thescreen box 49. At theforward-end, this] screen box is pivotallysupported by a swinging *a'rm 5|:

so that by oscillation ofthe armlfl during oscillation of the arm 65,the shaft 48 andarm .50, are

1 oscillated to vibrate the, screen box so'that'the beans pass throughthe screen 32 andthrough.

the screen 52 onto the screen tom of the box. The screen '53 small passtherethrough but this screen allowsculled beans, sand and small foreignparticles to pass therethrough onto the bottom of the box 49 which isprovided with which this waste material falls.

53 near the botis provided with A blower housing 55 is provided. asshown in 9 and is adapted to ,blow

Fig. (beneath the belt a continuous current of air over the top of thescreen 32 so as to blow all fine particles and waste material ofi fromthis screen as the beans are.

discharged thereon from the discharge rack and from the belt 9. l hisblower may be of any conventional type and comprises afan 56 secured tothe shaftfii and this shaft as shownin Fig. 1 is driven by abelt 58 fromthe pulley 59. The pulley 59 is secured to a shaft 60 and this shaft asshown in Fig. 7 is provided with a conventional fan 6! adapted to blowair from the housing 62 through the screen box to blow the dust and fineparticles out, of this box as the beans and dust fall therethroughduring vibrating action of the screen box.

This shaft fifi'is driven byn eans of abelt 63 shown in Figs. 1, 3, 5,.and 6 from a'pulley 64 secured to the main drive shaft I. By thisarrangement, both fans are driven and the shaft 51 ordinary grains. 7

From the foregoing description, it becomes evi-,

openings so that no'rmalsize'beans cannot a discharge slot 54' through.

for the fan 56 is provided with a pulley 65 shown in Fig. 2 and thispulley drives the belt 31 and shaft 35 to drive the belt 9 and themechanism shown in Fig. 6 for operating the discharge racks.

The oscillating armfifi for vibrating the screen box is shown moreparticularlyin Figs. 2 and 9 andla rod 65 connects. this arm with a bellcrank 18 and with an arm 61 which is connected to the bean dischargetrough 68 to vibrate this trough longitudinally. This trough as shown inFigs. 1, 4, and 5 is positioned beneath the discharge end of the screenbox so that the beans fall therein and travel down the sloping bottom ofthis disi charge trough into a hopper 69 from which they are carriedupwardly by the chain conveyer 1U and 8 into a compartment 12 having ashut-off slide '13- and provided with an open lower end 14 to which asack may be secured to receive the beans. When the sack is attached overthis opening 14,- the slide 13 may be drawn out to allow the beans tofall into the sack. The conveyer 70 is driven at the upper end by meansof a shaft to which a pulley i6 is secured and this pulley i6- isconnected by means of a belt 11 to'the pulley 64 onthe shaft I as shownin Figs; 1 and 5.

By changingthe screens in the screen box and the spacing of the teeth inthe shredders the ma chine may be arranged for threshing any of the dentthat the device is very efiicient in operation, will provide a compactand comparatively cheap machine for threshing beans or other grain, willdeliver absolutely clean beans to the discharge trough and provideadevice which accomplishes the objects described.

Having thus fully described my invention, its utilityand mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is y .In a bean threshing ma'ch'ine a hopper; a pair ofshredding drums rotatably mounted in the hopper and having a series ofradially extending pegs, a series of pegs extending upwardly from thebottom of the hopper beneath .each shredding drumythe hopper bottombeing provided with a multiplicity of bean apertures adjacent to andbetween'the pegs, a horizontal conveyer belt beneath the hopper,asloping shaker having the lower end extending between the hopper and theconveyer belt and .the upper end extending beyond the hopper, a seriesiof discharge racks,
